This Excel file contains individual-level pre‑ and post‑intervention data from a non‑randomized clinical trial that evaluated the effects of the Adapted Balance and Lower‑Limb Strength Exercise (ABLE) Training program on muscle strength, physical performance, and balance in older adults. Participants were assigned to two groups: community‑dwelling older adults (G1Comm) and institutionalized older adults (G2Inst). All variables were measured at baseline (time = 1) and after 12 weeks of training (time = 2). Structure of the dataset Each row represents one observation per participant per timepoint. The columns include: ID: Unique participant identifier. Group: 1 = community‑dwelling; 2 = institutionalized. Time: 1 = pre‑intervention; 2 = post‑intervention. Handgrip dominant (kg): Mean handgrip strength of the dominant hand. Handgrip non‑dominant (kg): Mean handgrip strength of the non‑dominant hand. Berg: Total score of the Berg Balance Scale (0–56). Sit: Five‑times sit‑to‑stand test (seconds). Vel: 4‑meter fast gait speed (m/s). SPPB: Short Physical Performance Battery total score (0–12). TUG: Timed Up and Go test (seconds). Purpose of the dataset The file allows replication of all statistical analyses reported in the manuscript, including group comparisons (G1Comm vs. G2Inst) and pre‑ vs. post‑intervention effects using generalized estimating equations. File format Microsoft Excel (.xlsx), single worksheet named “Tese”.
